Answers

Answer 1

Answer:

Relations B and E do not represent the function.

Step-by-step explanation:

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

If we closely observe relation B, and E i.e.

B) {(3,4), (4,5), (3,6). (6,7)}E) {(3,4), (4,5), (4,6)}

Relation 'B' IS NOT A FUNCTION

Relation B has duplicated or repeated inputs i.e. x = 3 appears twice times. we can not have duplicated inputs as there should be only 1 output for each input.

Thus, relation B is NOT a function.

Relation 'E' IS NOT A FUNCTION

Relation E has duplicated or repeated inputs i.e. x = 4 appears twice times. we can not have duplicated inputs as there should be only 1 output for each input.

Thus, relation B is NOT a function.

Therefore, relations B and E do not represent the function.

megan is trying to find the length of the segment using the Pythagorean Theorem


Part A : megan made one mistake in her work , which caused her to get the wrong answer what did she do wrong?

Part B : Calculate the correct length of the segment

Answers

Answer:

10

Step-by-step explanation:

To obtain the length of the segment :

a² + b² = c²

a = 8 ; b = 6

8² + 6² = c²

64 + 36 = c²

100 = c²

Square root of both sides :

Sqrt(100) = sqrt(c²)

10 = c

Mistake in the solution is that 6² = 36 and not 12

The budget for dances is $380

Step-by-step explanation:

If we know that the ratio between student government budget for dance and charity event is 5:7 this means that there is some amount of money that fits 5 times into the student government budget for dance and 7 times into the budget for the charity events. So in order to find what is the value of that among we divide $532.00 by 7, and then multiply that amount by 5 to get the budget for the dance events. So we do........

$532.00 / 7 x 5 = $76 x 5 = $380

If the measure of Angle B E C is (2 x + 3) degrees and x = 30, which expression could represent the measure of Angle A E D?

Lines A C and B D intersect at point E.
(4 x minus 3) degrees
(3 x minus 27) degrees
(5 x minus 33) degrees
(x + 43) degrees

Answers

Answer:

(3x−27)o

Step-by-step explanation:

we know that

m\angle BEC=m\angle AEDm∠BEC=m∠AED ----> by vertical angles

we have

m\angle BEC=(2x+3)^om∠BEC=(2x+3)o

The value of x is given

x=30

so

m\angle BEC=(2(30)+3)=63^om∠BEC=(2(30)+3)=63o

That means that the measure of angle AED is also 63 degrees

so

The expression that could represent the measure of Angle A E D is

(3x-27)^o(3x−27)o

because

For x=30

(3(30)-27)=63^o(3(30)−27)=63o

Answer:

(3x−27)o

First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).

Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function C(f) = 24f represents the number of cookies, C, that can be made with f cups of flour. Which set of ordered pairs represent points on the graph of C(f) = 24f?

Answers

Answer:

c(0) = 24*0 = 0  

c(8) = 24*8 = 192  

Your range is [0,192]

Step-by-step explanation:

Answer:

You have 8 cups of flour it takes 1 cup of flour to make 24 cookies the function c(f)=24f

c represents the number of cookies

f represents the cups of flour

You have 8 cups of  flour, we can use only 0 to 8 cups of flour.

so domain f is 0 to 8 cups [0,8]

Now we find the range

1 cup of flour to make 24 cookies

So 8 cups of flour = 24* 8 = 192 cookies

using 8 cups you can make 192 cookies

So number of cookies is from 0 to 192

Range is [0,192

10 A solid metallic cylinder of radius 14 cm and
height 21 cm is melted and recast into equal
small spheres each of radius 7/2 cm. Find then
number of spheres formed.​

Answers

Answer:

72 spheres are formed

Step-by-step explanation:

We start by calculating the volume of the metallic cylinder

Mathematically, we have this as;

V = pi * r^2 * h

V = pi * 21 * 14^2

V = 4116 π cm^3

The volume of each small sphere is;

V = 4/3 * pi * r^3

= 4/3 * π * 7/2^3 = 57.167 π cm^3

To get the number of small spheres, we simply divide the volumes

That will be 4116 pi / 57.167 pi = 72

What is surface area of a cuboid?

The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.

Given that, Yolanda makes wooden boxes for a crafts fair.

The dimensions of box are length= 5 inches, breadth = 3 inches and height = 2 inches.

We know that, the formula to find the toral surface area of cuboid is 2(lb+bh+hl)

Now, surface area = 2(5×3+3×2+2×5)

= 2(15+6+10)

= 2(31

= 62 square inches.

Therefore, the surface area of one box is 62 square inches.
